Application flled bipril 27, 1925. Serial No. 26,096

My present invention relates to a two piece radiator for a warm air furnace.

At one time the radiators for warm air furnaceswere commonly formed of; two sections separately'cast from separate patterns with the sections thereafter brought together to make a complete radiator including a central hollow dome and a ring spaced thereabouts with a flue connecting the dome and the ring The common defect in that construction was that the joint between the two sections did not remain permanently gas tight-under the severe conditions to which such an article is sub ected; Toavoid that dlsad'vani'age complete radiators have been made In one piece or from one casting; The disadvantages of sembled to make apermanent gasitight joint and so obtain the advantages of efiicient,

, economical and rapid machine manufacture incident to the casting of open sections'and yet have the advantage of a gas tight joint heretofore incident only toa one piece -radiator.

A further purpose is to provide a two-piece radiator having its sections of such form and relationthat the two sections are exactly simi lar except that the top section. will have a cap over the dome while the section that is to be the lmttom section will have cavity open at the bottom to fit the top of the combustion chamber section of the furnace. Through such close similarity in the form and construction of the two sections, I am enabled to make the castings for the two sections from the same main pattern, thus eflectinga great saving in the cost of necessary radiator for a furnace with the sections hava ing their meeting edges especially adapted to form or facilitate the forming of a gas tight and good mechanicaltjoint at all parts of the l ineeting edges of the two sections, and still further to have all parts of the meetingedges of the two sections provided with two spaced flanges oi: unequal height so as to forma broken joint when the sections are placed together and furthermore to have the oppositehalvesor other equal fractional parts of t-he sections for these dissimilar flanges reversely arranged so that two sections cast from the same main pattern may be brought together i to form a gas-tight and broken joint e j ect at all meeting edges of the two sections;

' Further pnrposes and advantages of my in vention will appear in the specification and claims herein.

Fig. 1 is a side elevationoi a two-piece radiator embodying invention as com-i pletely assembled and in; place upon the top of a combustion chamber-section of a furformed pursuant to my invention.

with said sections in opposing spaced slightly from each other;

Fig. 6 is a similar sectional view of said partswhen assembled. j l j t j Referring to the drawings in a more parposition but ticular' description, it will be said that I have illustrated my invention in radiators for fnrnaces 1n connectionwithithe common type of such radiators where the complete radiator it comprises a central hollowudome 10 and a hollow rings 11 spaced therefrom and, com-l municating therewith through a hollow flue 12. From the ring 11 there projects outwardly the smoke assage 13 adapted to receive the usual smoiepipe (not shown), this passage 13 usually andpreferablybeing located at the portionof the ring farthest away from the connecting fine 12.: i From the ring 11 there also extends outwardly the usual clean out passage 14, such passage being usually located as shown in thedrawings direct- 1y across from the flue 12. The parts of the dome and ring remote from the strong con ncctin g flue 12 are connected by bracing webs 33.

A radiator of this general type is formed. pursuant to my invention from two almost identical sections, namely: a bottom section 16 and a top section 17 the respective sections comprising the bottom and top half of the complete radiator are divided upon a central horizontal plane. Each section therefore provides an annular portion 18 U-shaped in cross section and a central cup shaped portion 19 with theseparts connected by a portion 20 U-shaped in cross section. These sections are exactly similar in construction. shape, size and arrangement except that the top section 17 has its central portion 19 closed away from its joint edges by a cap 21, which is at the top of the section when cast but at the bottom of the section as shown in Fig. 4; but

which cap becomes the top of thefdome when said upper section is turned Over to form the top of a radiator as shown in Figs. 5 and 6.

It will be understood that when the bottom section 17 is placed on top of a lower section 16, the U-shaped portions 18 will unite to form the ring 11 and the straight U-shaped portions20 will unite to form the complete flue 12 and that the central portions 19 will unite to form the dome 10c0vered at its top by the cap 21 and open at its bottom to rest upon and communicate with the feed section 22 of the furnace.

The meeting edges of the bottom section 17 and top section 18 throughout the dome 10, ring 11 and flue 12 clean out opening 14 and smoke passages 13 are thickened or widened as shown in a somewhat exaggerated form in the drawings and each edge is provided with two spaced flanges, one the high flange 23 and one the low flange 24, with a groove 25 therebetween. The arrangement is such that when the top and bottom section are properly assembled, the high flanges upon one section will come oppositethe low flanges on the other section and the low flanges upon the first section will come opposite the high flanges upon the second section resulting as shown particularly in Fig. 6 in obtaining what is commonly called a broken joint with the two grooves 25 uniting into one cavity which is filled prior to the assembling of the parts with a packing 34 usually provided in the form of an asbestos wick or cord supplemented with asbestos cement.

In order however, to produce this result with sections cast from the same main pattern, it will be obvious that the meeting edges have to be specially formed and particularly cannot have the high and low flanges extend continuously all around the section edges that are to form the ring and the dome and even the flue of the radiator. I accomplish the desired result however, by having the opposite halves (or other equal fractional parts) of each section have its high and low flanges reversely arranged. In the drawings I have shown as a convenient and the preferred con struction the reversal of these flanges in the opposite halves ofeach section. That is the high and low flanges are arranged in one relative position upon the left hand half of the castin as shown in Figs. 2, 3 and 4 while the flanges upon the right h and half are arranged in exactly the reverse order.

In other words, the high flange 23 for the outer wall of the radiator ring 11 on the left hand part of the casting is outside of the groove 25, that is farther from the center of the casting while on the right hand part of the ring this wall has its high flange inside of the groove 25. A similar reversal of the arrangement of the flanges is seen also on the inner wall of this ring in that the left hand half of the casting has its high flange inside of the groove that is towards the center of the casting from the groove while the corresponding right hand portion of the casting has its high flange outside of the groove. Similarly, the two halves of the upper edges or adjoining edges of the dome 10 and of the flue 12 have the high flange outside the groove on the left hand half and inside of the groove on the right hand half. This construction it will be seen results in the formation of a shoulder 27 facing to the left directly at the back of the inner wall of the ring 11 where the high flange 23 coming from the right outside of the groove 25 steps down to the low flange 24, coming from the left. To the inner side of the groove there is another shoulder 28 facing to the right made by the high flange 23 upon the left hand of the casting stepping down to meet the low flange 24 upon the right hand half of the casting. At the back of the dome a shoulder 29 faces to the right beyond the groove and a shoulder 30 faces to the left on the side of the groove towards the center of the casting. The presence of the smoke pipe passage 18 at the rear of the section and leading from the outer wall of the ring prevents the formation of such shoulders on the outer wall of the ring at the back. The presence of the flue 12 and clean-out opening 14 obviate corresponding immediate approaches to each other of the high and low flanges upon the forward half of each casting.

It will now be seen that when a top section as shown in Fig. 4 is turned upside down as in Fig. 5 over a bottom section 16 it will result in what was the right hand half of Fig. 4 becoming now the left hand half of the top section in its proper position as shown in Fig. 5 while the left hand half of the top section as shown in Fig. 4 will become the right hand portion of the top in its proper position as shown in Fig. 5. It will, therefore, be seen that these two castings have all the meeting edges of the walls with their high and low mo em flanges in such relative arrangement that the two sections ofthe radiator Will fit together and that at each joint the high flanges Willi tit against low flanges and the low flanges lit against high flanges Int this way a sovaillecl broken joint will be effected so that ii rope or wick of :ISljJtStOHWW aslwstoseenie nt may berendily placed in the circular or oval opening nmfde by the combining oh the two grooves. i

It Will also be seen that the un'angement of the high and low flanges is such as to pre vent the upper section from sliding atialli Preferably the said arrangement of double flanges on the meetingedges of iti'ietw osections is carried out even open the short out- Wardextensions forming the clean-out open ing 14 and the smoke pipe passage 13 as plainly indicatedinFig; 2. This further as sures a completely gas-tight joint at both sides of each of these short passages.

Spaced about" thefmeeting edges of each sectionthere are provided the proper number of vertically aperturedears 37 so arranged that whentwo of the-seetions are assembled each ear of a section will register with an ear on the other section-s0 {as to receive there through a bolt 38. Theseveral bolts andtheir; nuts 39 in anobvious manner provide means to draw and hold all parts of the two sections together after the necessary paekingQGof as bestos ro e orwiek supplemented with ce ment has en placed in the cavity formed by thetwo grooves 25. These ears project out Wardly from the walls of the dome 10 and fine 12 and from the-outer wall of theirin 11 and inwardly fromthe inner wallof the ring.

Preferably the axis ofthe apertures int-he ears fiT encroach somewhat into the general path of the groove 25 so as not tohavethe earsproject too 'iiarfrom the casting, At these points however the grooves are enlarged or widened sons to providea space all around the bolts38 which spaceisfilled with the packing-26 to-further assuiea gustigh'tjoint: at theseplaces. p t 3 An enlargement or 111 40 is provided upon the outer end of the clean-out passage 14 at its right hand wall as seen in Fig; 2 and through this lug is provided a horizontal hole 31. A corresponding top seetion willaccordingly providea similar lug at the letr: hand side of the clean-out passage as seenin Fig, 1. These aperturedlugs afford a ready means for boltinga collar (notshown) to the completed radiator. A similar single lug 32 with a hole therethrough upon the left hand side of the sinokepassage of the section as seen in Fig. 2 provides inthe complete two-section radiator a pair of similarly options. 1
